Passing in a string makes this trickier, as I guess you've already 
realized. What you're doing in

context.directory_context.objectValues('Image')

is trying to call a string (directory_context) like an ObjectManager. 
Not going to work. Python lets you get away with a lot, but not that much.

As suggested previously, you can turn the string into an object by 
restrictedTraverse(). In similar situations, involving non-traversable 
attributes, you might use Python's getattr() built-in.
